The family of a Melbourne woman who died suspiciously overseas two years ago should be given as much government assistance as possible, Bill Shorten says.
Elly Warren's loved ones are still searching for answers as to why a fit and healthy 20-year-old was found dead near a toilet block in Mozambique in November 2016.
A bungled investigation from police in the African country has confused and upset the family, while the Coroners Court of Victoria has been investigating but is yet to find a determined cause of death.
The Labor leader said he could not "imagine the pain" Elly's family is going through not knowing why or how she died.
The family believe the only conclusion for her death is murder.
Frustrated by a lack of action from Mozambique authorities, Elly's mother Nicole Cafarella and stepfather Dave Cafarella have called on Prime Minister Scott Morrison to intervene.
Her father Paul Warren recently travelled to Mozambique searching for answers.
"I would like to see what we can do to assist him in his search for truth," Mr Shorten told reporters in Perth on Friday.
"I think a father's pain for a girl who is Australian means that where we can help, we should help.
"I respect the fact that the family has made such an effort. This is something where a modest effort from the government wouldn't go astray."
A Change.Org petition seeking justice for Elly has grown to more than 27,000 signatures since being started by the family last weekend.
Australian officials cannot go into another country to investigate the death of a citizen but governments are able to invite foreign authorities in to help during exceptional circumstances.
"We want the Australian government to assist us by holding high-level talks with Mozambique, with the view to having Australian detectives assist the Mozambique police with their investigation of Elly's death," Ms Cafarella told AAP this week.
The Australian Federal Police, the Department of Foreign Affairs and Trade and Victoria Police have all been involved at varying levels, but have not found out what happened.
